Engineer Trainee
TEXMO INDUSTRIES / TARO PUMPS
09.2021 - 03.2022
- Designed and developed from scratch to prototype (design, PCB layout, testing) a model of an intelligent electronic control panel for 1 PH and 3PH pump motor system that uses a wireless communication module for GSM and GPRS based monitoring and control. Implemented using two variants, one with a step down transformer and a flyback SMPS.
START UP INITIATIVE
SELF
10.2020 - 09.2021
- Took an initiative to develop an indigenous motor controller for a 48V battery system with the help of colleagues from BOSCH, my project professor and industry experts. Pitched the idea in PSG start up cell and was provided with incubation for 6 months, but left the idea because of financial constraints.
- Actively working to patent the concept of the indigenous motor controller.
Internship
